Polyimide composites are being evaluated for use in lightweight support structures designed to preserve the ideal flow geometry within thin shell combustion chambers of future space launch propulsion systems. Principles of lightweight de... JC Thesken,M Melis,E Shin,... 被引量: 2发表: 2004年 ...
a short time when HFRS works at the design current.Thus,a plug system design similar to the Super-FRS at GSI[2]has been proposed to solve the problem.One of the technical challenges in HFRS beam line is the vacuum system design,which can work safely at the exposure of high levels of ...
Laser-induced damage on the tensile side of vacuum-barrier fused silica optics can result in catastrophic fracture. This fracture can lead to two possible modes of failure: a benign failure resulting in a slow air leak into the vacuum chamber or an implosion. In previous work, they measured ...
The SPASCHARM experiment is aimed at a systematic study of the nucleon spin structure and the spin dependence of the strong interaction of antimatter and matter with matter at energies up to 45 GeV. As part of the first stage of the experiment, the study of the spin properties of hadrons ...

A vacuum and gas control system permits evacuation of the chamber and the subsequent introduction of any (dried) gas mixture at partial pressures between 1 mbar and several bars. The minimum CCD temperature was found to depend on the surrounding MASC temperature and atmosphere. A vertical shift ...
A neutron monitor using micro-fission chambers to be installed inside the vacuum vessel has been designed for the International Thermonuclear Experimental ... T Nishitani,K Ebisawa,LC Johnson,... - 《Review of Scientific Instruments》 被引量: 25发表: 1998年 ...
Compression of an O-ring creates an air-tight seal that can withstand high pressures and temperatures. These are often used in regions where high-pressure differentials occur such as inlet piping, or for the doors of vacuum chambers integrated into a glove box system. Reducing Ingression: ...
Solar methods are much more unconventional, they require a large free space in the rooftop for the sun to heat dark long vacuum sealed tube in which interior flows cold water via convection currents, this method's performance excels in countries which have a great density of solar energy but...
